I generally will give a firm the benefit of the doubt and discount 1 or 2 bad reviews. When there is a consistent negative theme in the reviews then I trust it completely. I have turned down several interviews because of Glassdoor reviews and have bought up bad reviews during interviews. Everytime the HR person has confirmed that the reviews had truth to them and that they were working on the issue or it was already fixed.
